Abstract

Rashwan, S. M., Al Khalaf, H. N., Al Hammad, M. I., Abdel-Baky, M. H. and Azab, A. H. 2001. Determination of sheep pox circulating neutralizing antibodies in immunized sheep and goats in the North Region of the Kingdom of Saudi Arabia. J. Appl. Anim. Res., 19: 233–235.

As a first field trial to evaluate the sheep pox vaccine efficacy under farm conditions, sheep pox virus-neutralizing antibodies were determined in vaccinated sheep and goats of different breeds, ages and sexes in one of the biggest mutton farms in the north region of the Kingdom. The results exhibited 100% post-vaccinal serum neutralizing antibodies with a titre range of 1.2 to 2.1 log 10 in sheep and 1.2 to 1.8 log 10 in goats.
